Kennametal 1160901 Turning Insert CNGP434 KC730 Carbide

Product Description

The KENNAMETAL 1160901 is a solid carbide turning insert in the CNGP434 geometry, coated with TiN via a PVD process and assigned the KC730 manufacturer grade. It carries an 80-degree diamond (rhombic) shape with a 0.5-inch inscribed circle, a 3/16-inch thickness, and a 1/16-inch corner radius. The negative rake and neutral hand make it well-suited for high-wear and moderate-toughness applications. Part of the KENLOC series, this insert is intended for professional machinists running turning, facing, and boring operations on CNC or manual lathes.

This insert targets medium machining conditions on steel, stainless steel, cast iron, and superalloys including titanium. The KC730 grade is engineered for high wear resistance to moderate toughness across P, M, and K workpiece material classifications. With four available cutting edges and a honed cutting edge style, it is a practical multi-use option for production shops running varied workpiece materials. The KENLOC clamp-and-pin holding method provides secure seating in compatible toolholders. Maximum depth of cut is 0.0492 inch (1.25 mm).

Installation Notes

Installation is performed by qualified machinists or CNC setup technicians. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct clamp screw torque procedure specified by the toolholder manufacturer for KENLOC-style clamp-and-pin seats. Inspect the insert pocket and seating surfaces for debris or damage before seating a new insert.
